Latch flip-flop

Block name

BD53_LATCHFLIPFLOPNODE

ST call

PROGRAM TEST_BD53
VAR
   BOOL1, BOOL2, BOOL3, BOOL4, BOOL5, BOOL6, BOOL7: BOOL;  
    FB : LIB.CORE.V1_0.BD53_LATCHFLIPFLOPNODE;
END_VAR
   FB.IN[1]:=BOOL2;
    FB.IN[2]:=BOOL3;
    FB.IN[3]:=BOOL4;
    FB(ENABLED:=BOOL1);
 BOOL5 := FB.OUT[1];
 BOOL6 := FB.OUT[2];
 BOOL7 := FB.OUT[3];
END_PROGRAM

Library

LIB\CORE

Version

V1.0

Description

The block is a gate for logical signals.

Inputs

Input Type Description Default value
ENABLE BOOL If enable=true then out0=in0,…False
IN0,IN1,..,IN15BOOL Inputs, individually
IN MULTIIOBOOLInputs array [False]

Outputs

Output Type Description
OUT MULTIIOBOOLOutputs array
OUT0,OUT1,..,OUT15BOOL Outputs, individually

Function

The block is a gate: if enable=true then all inputs are copied to outputs. If enable=false the outputs keep the last value. Note that the ST indeces range is 1 to 16 rather than 0…15.
